Tell reads the accounts, posts and contracts on your X timeline so it can label them. To do that it sends what is on your screen to our API and gets labels back.

The short version
- We never collect your direct messages, bookmarks, notifications, passwords or wallet.
- Nothing about your own account is ever sent: not your posts, not replies to you, not posts that mention you.
- We do not sell data and we do not run ads.
- One switch in the extension turns off sharing of the public posts you scroll past.

The extension
It runs only on x.com and twitter.com. It asks the browser for one permission, storage, plus access to those two sites and to our API (api.usetellcoin.com).

Labels. To label a post, the extension sends it to our API: the author's public handle and id, the text, links and contract addresses. The request carries no account, login or device identifier.

Sharing. With the sharing switch on, which is the default, the public posts and accounts you scroll past are kept so checks get better for everyone. With the switch off, posts are still sent to get their labels but nothing is stored. The extension always leaves out your own profile, your posts, replies to you and posts that mention you, and never reads direct messages, bookmarks, notifications or settings.

On your device. Your settings, today's counts and the list of recently flagged posts stay in your browser and are never uploaded. Removing the extension deletes them.

Who else sees it
Our hosting provider runs the API. Prices come from public market data and blockchain nodes, which never receive anything about you. We will disclose data only if the law requires it.

Keeping and deleting data
Public X data and labels are kept as long as they are useful for flagging accounts and coins. To see, correct or delete data about you, or to ask for a label on your account to be reviewed, write to contact@usetellcoin.com. Corrections and removals are free.

Tell is not meant for children under 13. If this policy changes, the date at the top changes with it.
